AUTOMOBILE-RADIATOR.

Specification of Letters Patent.

Patented Apri -8, 1908.

Application filed. November 18, 1907. Serial No. 402637.

common construction do usually begin toleak; another. object is to produce a radiator which may be easily got at when any repairs are re uired.

In t e drawing Figure 1 is a front elevation partly broken away of a radiator embodymg the invention. Fig. 2 is a side elevation thereof; and Fig. 3 is a sectional view in the plane of line 33 on Fig. 1.

Referring to the parts by letters, A represents the lower radiator tank which is made of sheet metal. It has two inlets a, a, through its to near the sides thereof. It also has an out et pipe C through which water may [low from the tank to the engine casor other parts to be cooled by said water. B represents the upper tank which is also made of sheet metal. There are two outlets i), b, in the bottom of this tank near its sides;

and filling tube b is connected with the, top of said tank. Two metal side plates or headers D, D, extend between these two tanks i being riveted or soldered or otherwise connected with the bottom of the upper tank and the top of the lower tank, the points of connection being inside of the openmgs a, b, in the top and bottom tanks respectively.

A large number of horizontal radiator tubes E extend from one side plate to the,

i left side and the bottom cap-on t right side,

are of such size that they cover the ends of four rows of tubes. These caps have marginal flanges g which lie against the side plates D and are solderedthereto. The upper return-bend caps on the left side of the radiator covers the ends of only two rows of tubes, and the bottom return-bend cap on the right side covers only two rows of tubes and serves to connect'them with the inlet a of the tank.

It is quite clear that as water enters the radiator through pipe M it will be compelled to flow downward, passing to the right through two rows of tubes, then to the left through the next two rows of. tubes, then to the right through the next two rows of tubes, and so on until discharged into the lower tank.

The radiator as far as above described, is of common construction; but it has several objectionable characteristics of construction which it is the object of the present invention to correct. For example, if any of the soldered joints between the return-bend ca s G and the side plates D should begin to eak, the water assing through the opening thus two long cover plates H are provided. These plates are connected with the upper and lower tanks outside of the opening'a, b, and the vertical edges of these plates are soldered or otherwise connected with the two outwardly extended flanges d, d of'the sidev plates D, I), so as to embrace and cover all of the return bend plates E. If, now, there shouldb'e any break in the joints between the return bend platesE and the plates D the water escaping will not be lost but would simply flow into the'pockets formed by the plates H and thence in time into the lower tank. In filling the circulating system with water, the cap 12 ot'the filling tube It is re- .moved and water poured into this tube, it

the

will flow from the upper tank through ockets inclosed by the plates H into the ower tank and thence up through the various rows of tubes.

The radiator as above constructed rests in connected with members-of the automobile frame. tended lugs f The upper part of the radia- -a cast metal cradle F which forms the bottom of the radiator frame. It has laterally extended arms f by the use of which it'may be On these arms are upwardly ex 'tor frame is a single piece of sheet metal K bent into the form shown; and the ends of this piece are clamped to the lug f by means of clamping plates is held onby screws. A sheet meta plate J is soldered to the front "edgeof the cast metal cradle F and extends up so, as to conceal the tank A, and give a goodfinish-to the device. The upper ends of this plate are soldered to the lower ends of the frame member K. .T is construction of Having describedv my invention, 1 claim:

' I. In an automobile radiator, the combination ofan upper tank having outlets through people its bottomnear its sides, a lower tank having inlets through its top near its sides, side members secured to said two tanks inside of. said inlet and outlet openings, rows of horizontal tubes eXtendin between and assing through said side mem ers and secured thereto, return bend plates secured to said side members and covering a plurality of rows of tubes, and cover plates secured to the bottom of the upper tank and to the top of the lower tank outside of said openings therein, find secured at its side edges to said side memers.

2. In an automobile radiator, the combination with the radiator proper and a frame comprising a cast metal cradle on which the radiator rests, which cradle has laterally extended arms and upwardly projecting lugs and an up er member of approximately inverted U s ape, the lower ends of which are I clamped to said lugs.

- In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
